Crystallization of the Kob-Andersen binary Lennard-Jones liquid

At density 1.2 the Kob-Andersen binary Lennard-Jones liquid partly crystallizes in the temperature interval [0.39, 0.44] after typically 10-100 microseconds (Argon units). The crystallization is initiated by a phase separation where the large (A) particles cluster in a volume void of B particles. We investigate a modification of the Kob-Andersen system where the attraction between particles of the same type is removed, thus disfavoring phase separation. We have not been able to crystallize this new system.
